Abstract

The pacemaker comprises an indicating micro-electrode in association with a reference electrode and inserted in the patient's body in contact with the blood to measure the pH of the blood. This measuring device is connected, through an impedance adapter, to the input of an amplifier which amplifies the mV output of the measuring device by at least a thousand times, and the output of the amplifier is supplied to the input of a transistorized oscillator generating signals of variable frequency in accordance with its input. The oscillator is connected to a cathode follower to furnish the energy necessary for the impulses for the cardiac stimulation which, as known, are applied to an electrode inserted in the cardiac muscular tissue of the ventricle of the heart. A limiter is connected to the input of the amplifier. The amplifier may be either a direct current amplifier or an alternating current amplifier.
